How can I change the type of a new added field in the Expression Evaluator?
Because if I add a field like this:

Then the field is defined as a string. But I need to have it as DATETIME
I know I could just not add this field but my goal is to make the pipeline creating not existing tables if needed.
So I need to declare all attributes, even they are empty.
Thanks
